ObjectiveTo investigate the mechanism by which Luoshi Neiyi prescription treats endometriosis （EMs） through the Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） signaling pathway. MethodsAnimal experiments were conducted with 50 female SD rats， which were randomized into a sham operation group （10 rats） and a modeling group （40 rats）. An autologous endometrial transplantation method was used for the modeling of EMs. The 36 successfully modeled rats were randomly allocated into four groups （n=9 each）： The model group， the low-dose （7.87 g·kg^-1） Luoshi Neiyi prescription group， the high-dose （15.74 g·kg^-1） Luoshi Neiyi prescription group， and the dienogest （0.20 mg·kg^-1） group. The physiological status and ectopic lesion volumes of rats in each group were observed. Hematoxylin-eosin （HE） staining was used to observe the morphology of the eutopic endometrial tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of inflammatory factors including interleukin-1β （IL-1β） and prostaglandin E₂ （PGE₂） in the serum of EMs rats. Immunohistochemistry was used to detect the expression of matrix metalloproteinase-9 （MMP-9） and vascular endothelial growth factor A （VEGFA） in the eutopic endometrial tissue. Western blot was adopted to determine the protein levels of TLR4， myeloid differentiation factor 88 （MyD88）， phosphorylated nuclear factor-κB （p-NF-κB）/NF-κB， MMP-9， and VEGFA in the eutopic endometrial tissue. In the cell experiments， the cell-counting kit-8 （CCK-8） assay was employed to screen the optimal concentration of Luoshi Neiyi prescription-containing serum， and a scratch assay was performed to assess the migration ability of iheESCs cells. Interventions with Luoshi Neiyi prescription-containing serum， resatorvid （TAK-242， a TLR4 inhibitor）， and lipopolysaccharides （LPS， a TLR4 agonist） were conducted， and Western blot was used to detect the expression of proteins related to the TLR4/NF-κB signaling pathway. ResultsThis experiment successfully replicated 36 EMs rat models. Compared with the sham operation group， the model group exhibited visible ectopic lesions on the abdominal wall and an increase in the writhing response score （P<0.01）. Furthermore， HE staining revealed the model group exhibited a thickened eutopic epithelium， stromal cell disarrangement， and evident infiltration of inflammatory cells. In addition， the model group showed elevated serum levels of IL-1β and PGE₂ （P<0.05， P<0.01）， increased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue （P<0.01）， and up-regulated protein levels of TLR4， MyD88， p-NF-κB/NF-κB， MMP-9， and VEGFA in the ectopic endometrial tissue （P<0.05， P<0.01）. Compared with the model group， all treatment groups exhibited a reduction in the ectopic lesion volume （P<0.01）. Furthermore， the writhing response scores were decreased in the high-dose Luoshi Neiyi prescription group and the dienogest group （P<0.05， P<0.01）. The pathological state of the ectopic endometrial tissue was alleviated to varying degrees in the treatment groups. Low-dose Luoshi Neiyi prescription reduced serum PGE₂ levels， and high-dose Luoshi Neiyi prescription and dienogest decreased serum IL-1β and PGE₂ levels in EMs rats （P<0.05， P<0.01）. The treatment groups showed decreased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue （P<0.05， P<0.01） and down-regulated protein levels of TLR4， MyD88， p-NF-κB/NF-κB， MMP-9， and VEGFA in the ectopic endometrial tissue （P<0.05， P<0.01）. The cell experiments showed that 5%， 10%， and 20% Luoshi Neiyi prescription-containing sera significantly reduced the viability and inhibited the migration of iheESCs. Compared with the control group， 5%， 10%， and 20% Luoshi Neiyi prescription-containing serum groups and the TAK-242 group showed reduced protein levels of TLR4， MyD88， p-NF-κB/NF-κB， MMP-9， and VEGFA （P<0.01）. Compared with the control group， the LPS group showed increased expression of the above proteins （P<0.01）. Compared with the LPS group， the LPS+5%， 10%， and 20% Luoshi Neiyi prescription-containing serum groups showed reduced expression of the above proteins （P<0.05， P<0.01）. ConclusionLuoshi Neiyi prescription may modulate the TLR4/NF-κB signaling pathway to reduce the inflammatory response and histopathological damage in the eutopic endometrium and suppress the adhesive， invasive， and angiogenic biological processes in the ectopic endometrial tissue， thereby exerting its therapeutic effect on EMs.

ObjectiveTo investigate the current status of HIV-related health service uptake among cross-border couples (Chinese husbands and Myanmar wives) in Dehong Dai and Jingpo Autonomous Prefecture (hereinafter referred to as Dehong Prefecture), and to provide evidence for optimizing HIV prevention and control strategies in border areas. MethodsA cross-sectional survey was conducted from September 2022 to September 2023 among 14 662 cross-border couples (Chinese husbands and Myanmar wives) in Dehong Prefecture. Data on sociodemographic characteristics, HIV/AIDS knowledge awareness, and utilization of HIV-related health services within the past year were collected. Multivariable logistic regression was used to analyze factors associated with HIV testing uptake among husbands and wives. ResultsA total of 29 324 individuals (14 662 couples) were included. The overall awareness rate of HIV/AIDS was 82.09%, with the rate among husbands significantly higher than that among wives (85.17% vs. 79.01%, P<0.001). Overall, 94.98% of participants had received at least one HIV-related health service, and the HIV testing rate in the past year was 65.52%. Multivariable logistic regression analysis showed that, compared with participants married for 0‒3 years, those married for 4‒10 years and ≥11 years were more likely to have received HIV testing. The corresponding ORs were 1.344 (95%CI: 1.187‒1.521) and 1.381 (95%CI: 1.211‒1.574) among husbands, and 1.308 (95%CI: 1.155‒1.481) and 1.344 (95%CI: 1.178‒1.533) among wives, respectively. Compared with those holding a marriage certificate, those possessing a border marriage registration certificate were positively associated with HIV testing uptake, with ORs of 1.710 (95%CI: 1.575‒1.857) among husbands and 1.700 (95%CI: 1.565‒1.847) among wives. Compared with illiterate participants, those with primary school education showed lower testing rates, with ORs of 0.738 (95%CI: 0.650‒0.837) among husbands and 0.827 (95%CI: 0.766‒0.891) among wives. Additionally, a history of sexually transmitted diseases (OR=3.656, 95%CI: 1.243‒15.589) and participation in the New Rural Cooperative Medical Scheme (OR=1.51, 95%CI: 1.179‒1.935) were independently associated with higher testing rates among husbands. ConclusionThe overall utilization of HIV-related health services among cross-border couples in Dehong Prefecture is satisfactory, but significant gender disparities exist, with foreign wives showing lower rates of knowledge awareness and lower proportions obtaining such knowledge through certain channels compared with their Chinese husbands. Couples with shorter marriage duration, those with primary school education, and those not included in the border marriage registration system are vulnerable groups with lower HIV testing uptake. Future interventions should prioritize cross-border marriage families at the early stage of entry and in the newly married period. Based on the border marriage registration management system and primary healthcare networks, health education and HIV testing services targeting foreign spouses should be strengthened to improve service accessibility and equity.

Objective:To explore the anti-reflux effect of transverse fan-shaped groin formed (TFGF) when the residual stomach is large (the small curvature ≥10 cm).Methods:Twenty-four patients with residual curvature ≥10 cm after PG were treated with TFGF continuously from Nov 2020 to Dec 2023 in this study. The cohort included 20 patients with Siewert type Ⅱ adenocarcinoma of the esophagogastric junction and 4 patients with achalasia of cardia. Reflux disease questionnaire score gastroesophageal reflux disease questionnaire score and gastroscopy Los Angeles score were used to evaluate the anti-reflux effect and postoperative nutritional parameters (hemoglobin, protein and body weight).Results:The reconstructive operation time of adenocarcinoma of the esophago-gastric junction and achalasia of cardia was (20.0±5.1) min and (18.3±4.7) min, respectively. reflux disease questionnaire, gastro-esophageal reflux disease questionnaire and gastroscopy indicated GERD in 3 patients and 8% in 2 patients at 24 months. At follow-up, one patient transitioned from grade B to grade C based on the Los Angeles score at 12 months; 24 months after surgery, one patient's gastroesophageal reflux symptoms resolved and the Los Angeles rating was downgraded from B to A. Nutritional indicators (hemoglobin, protein and body weight levels) all showed a downward trend at 6 months and an upward trend at 24 months.Conclusion:TFGF has the advantages of simple operation, and effective prevention of postoperative gastroesophageal reflux for patients with lesser residual curvature ≥10 cm after PG.

Objective:To investigate the effect of age factor on glymphatic function in patients with Parkinson′s disease (PD) and its potential correlation with overall cognitive performance based on diffusion tensor imaging analysis along the perivascular space(DTI-ALPS) index.Methods:The study was cross-sectional. Clinical and imaging data of 77 PD patients (PD group) who attended the Provincial Hospital of Shandong First Medical University from October 2021 to June 2024 were retrospectively analyzed. In the same period, 30 healthy volunteers matched by age and gender were collected as the normal control (NC) group. All subjects underwent MRI scanning and DTI-ALPS index was calculated based on diffusion tensor imaging. Cognitive functions of 46 patients in the PD group were assessed using the mini-mental state examination (MMSE) and montreal cognitive assessment (MoCA) scores. Independent samples t-tests were used to compare the differences in DTI-ALPS index between the PD and NC groups. After adjusting for confounders, the relationship between DTI-ALPS and age was explored using partial correlation analyses, multiple linear regression models. A mediation model was further developed to explore the mediating effect of DTI-ALPS index between age and cognitive function scores. Results:The DTI-ALPS indices of PD and NC groups were 1.66±0.20 and 1.44±0.17, respectively, and the differences were statistically significant ( t=5.27, P<0.001). The age of patients in the PD group was negatively correlated with the DTI-ALPS index ( r=-0.54, P<0.001), and age (β=-0.467, P<0.001) was an independent influencer of DTI-ALPS index. The DTI-ALPS index was positively correlated with MMSE scores ( r=0.53, P<0.001) and positively correlated with MoCA scores ( r=0.56, P<0.001). The mediation model showed that the DTI-ALPS index fully mediated between age and MMSE scores and partially mediated between age and MoCA scores, with an effect share of 33.25%. Conclusion:Age is an independent risk factor for impaired glymphatic pathway in PD patients, and it may induce cognitive decline in PD patients by exacerbating glymphatic pathway impairment.
